The external teeth of CLZ type gear coupling are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The center of the spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. The drum-shaped gear coupling can allow larger angular displacement (compared to the straight-tooth coupling), which can improve the contact conditions of the teeth, increase the torque transmission capacity, and prolong the service life.The contact state along the tooth width when there is angular displacement.
    When CLZ type gear coupling is working, the two shafts produce relative angular displacement, and the tooth surfaces of the internal and external teeth periodically slide relative to each other in the axial direction, which will inevitably cause tooth surface wear and power consumption. Therefore, the gear coupling needs to be Work in a good and sealed state.Gear couplings have small radial dimensions and large load-bearing capacity. They are often used in shafting transmissions under low-speed and heavy-duty conditions. High-precision and dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shafting. transmission.Because the angular compensation of the drum gear coupling is greater than that of the straight gear coupling.
   CLZ type gear coupling has good impact bearing performance, but high requirements for tooth surface contact stress and tooth root bending fatigue strength. If we adopt special structure, special materials and special processes, then this coupling can meet the requirements of large-diameter rolling pipes. Machine requirements. CLZ type gear coupling: gear coupling is a rigid-flexible coupling. The gear coupling is composed of an inner gear ring with the same number of teeth and a flange half coupling with external teeth.
